Hello Robert,

Wonderful pictures of your Bomarea...... I wish I could grow them here but several attempts failed, they cannot cope with our hot summers....

So you probably can't grow the cloud forest Passifloras either then. They say that cool night temperatures are ALSO needed.

It is interesting that they seem to grow and flower about the same year-round here, not minding the winter rains and temps to near freezing, while the deciduous species go dormant in mid-fall.

in damp cool San Francisco, where a big Passiflora X Oaklandia is about to get moved or removed because it is overly vigorous, requiring bimonthly trimming to keep it from blocking the driveway from the arch trellis that is threatening to collapse under the weight.

Taken in the spring.

Thank you for sharing

The flowers of rupicola are double in size or more, and the corona is expanded, a bit like a disk,or like a very 'open', almost convex bowl. And the leaves are thinner and not always upright, usually not so glaucous. Yes, it almost always bears only one flower, but that's not a reliable trait to tell apart nany species.

Calcicola can have 1-3 flowers, which are quite small like in scaberulus (but scaberulus has quite different leaves). These very plants were sent to me from NW Portugal (no permit needed) and some had one, others 2, and a few three flowers. Now they are in a very different climate. They normally bloom in March - April.

I have always failed in germinating rupicola, it seems that it needs a too acid substrate that I can't recreate here. For these calcicola I brought ground pink granite from a beach in the Costa Brava, 450 km to the North, and earth  + lava chippings from a beech forest on volcanic rocks at the foot of the Pyrenees, 100 km more to the NE.

But here is true rupicola:

It seems that some / several nurseries (Beth Chatto, etc) have been offering calcicola as rupicola.

I have read that Narcissus calcicola differs from N. rupicola in having several flowers per stem, while N. rupicola has only one, like the plants in Carlos's photo. The ones I have grown for many years (a John Blanchard seed collection in the 1990s) as N. calcicola usually have three flowers per stem. Comments?

Try a dark background like a piece of black paper.

Narcissus calcicola. it blooms in March or April in habitat. My phone refuses to focus well on yellow flowers.

My evergreen Bomareas don't have an off season for blooming...4 of the 5 big ones are going off right now.

On a lighter note, received one of these as a holiday gift. (This image was taken at HD.)
